USB: ehci: minor ISO updates, always support split ISO
Small updates to the EHCI driver's ISO support:
- Get rid of the Kconfig option for full speed ISO. It may
not be perfect yet, but it hasn't appeared to be dangerous
and pretty much every configuration wants it.
- Instead of two places to disable an empty periodic schedule
after an ISO transfer completes, just have one.
- After the periodic schedule is disabled, we can short-circuit
the schedule scan ... it can't possibly have more work to do.
Assuming a typical config with split iso enabled, the only change
in behavior should be almost unobservable: quicker termination
of periodic scans when the schedule gets emptied.
